Hi all, I was using a NAND flash from ST Micro, 512 Mbit, with no problems in U-boot-1.2.0.
So I upgraded this nand to a 1 Gbit, also from ST Micro. But now U-boot read only zeros. In linux 2.6.26 both NANDs works. NAND is connect in Freescale Local Bus UPM. U-boot finds the NAND normally: NAND: 128 MiB In: serial Out: serial Err: serial And the Chip ID is correct in nand_ids.c (dont know the other options): {"NAND 128MiB 3,3V 8-bit", 0xF1, 0, 128, 0, NAND_SAMSUNG_LP_OPTIONS | NAND_NO_AUTOINCR} Before I start patching, any hints if could be in nand core or fsl upm driver? Or if NAND1G have some peculiarity? Cause I didnt see in datasheet anything that called my attention. NAND part numbers: NAND512W3A NAND01GW3B Cheers, -- Alemao _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
